In this post I will show you a couple of light box designs that I have built. They can give you ideas on ways you can build yourself a light box.

This first box has a built in dimmer switch and uses a dimmable LED 60 watt bulb. You could make something less complicated if you put the dimmer switch in a separate box. This box also makes you flip it to expose the circular light box for sighting reeds through the slot to check closure. I’ve now eliminated the need to flip the box by building in a sliding door on the lower portion of the box. You will see this in the next box when you scroll down to access the video on another box I built.

BTW – If you don’t have my hot rod your harmonica video downloads you may find it a little hard to understand the need for a light box and also how to use them. Once you see these videos you will understand how much guesswork they take out of the customizing process and why I never do the work without one…

It is a 4″ x 9 1/2″ box on a platform that allows me to pick it up and swivel it around. The dimmable 60 watt LED bulb and dimmer switch are in the same box. I have a recess routed out to make it easy to use a wrench for centering when checking reed / slot fit. The knob on the side is an off on switch and you rotate it to dim or brighten the light.

Box #2

This box uses a sliding door to open up a light source that reflects down on a sheet of paper for sighting reeds through the slot.

The box was too small to include a dimmer switch, but you could add one in a separate box.
